BP has won a 100% interest in the North Arafura oil and gas production sharing contract (PSC), onshore Papua Province.
The PSC was signed on Friday in Jakarta by representatives of the Indonesian Government and BP.
"BP is very pleased to expand our position in Papua, an area with huge potential in its people, culture and natural resources," said BP president for Asia Pacific Exploration & Production BP William Lin.
The North Arafura PSC is located on the coast of the Arafura Sea, 480km south-east of the BP-operated Tangguh plant, covering an area of 5,000km².
BP expects to commence seismic operations on the block soon.
